HERMAN R. SAXON, OF TOLEDO, OHIO, ASSIGNOR, BY MESNE ASSIGNMENTS, TO ELEC TRIO AUTO-LITE CORPORATION, OF TOLEDO, OHIO, A CORPORATION OF DELAWARE.

LAMP.

Application filed March 10, 1916. Serial No. 83,315.

To all whom it may concern:

Be it known that I, HERMAN R. Saxon, a citizen of the United States of America, residing at Toledo, Lucas County, Ohio, have invented certain new and useful Improvemerits in Lamps, of which the following is a specification.

The present invention relates to lamps adapted more particularly for use as head lights on automobiles and has for one object to provide improved mounting brackets by which the lamps or headlights are supported.

A further object of the invention is to provide a simple and economical form of securing and locking means for mounting and retaining the reflector and lens ring upon the housing.

Further objects, and objects relating to economies of manufacture and details of construction, will definitely appear from the detailed description to follow:

I accomplishthe objects of my invention by the devices and means described in the "following specification. My invention is clearly defined and pointed out in the appended claims.

A structure constituting a preferred embodiment of my invention is illustrated in the accompanying drawings, forming a part of this specification, in which:

Fig. 1 is a front elevation, with parts broken away, of an embodiment of the invention in a projecting headlight such as may be used as search-lights, spotlights or motor vehicle headlights;

Fig. 2 is a fragmentary view of aportion of the housing of the lamp of Fig. 1;

Fig. 3 is a section on the line III-III,

Fig. 1;

Fig. 4 is a section on the line IV-.-IV, Fig. 1 with the trigger in unlatched position;

Fig. 5 is a section on the line V V, Fig. 1, showing the trigger in latched position;

Fig. 6 is a view similar to Fig. 5, showing the holding means or lens ring mounting of a somewhat different form from the showing in Fig. 5;

Fig. 7 is a view of the mounting bracket blank for the housing; and i Fig. 8 is aiperspective View of the mounting bracket shaped up -and ready to be fixed in the housing.

The lamp comprises the housing 1 having the mounting brackets providing the cylindrical hump portion 2 provided with the pair of parallel legs 3 extending therefrom. .lhese legs 3 are held in spaced relation by the pairs of inwardly extending spacing means 4 terminally completing the eye portion of the hump 2. The legs 3 terminate in the opposite pair of relatively spaced and parallel base portions 5. light weight sheet metal lamp housing supporting bracket is thrust through the wall of the housing 1 and due to its yielding or springy nature snaps into position upon the housing where it is fixed by spot weldin the raised portions 6 to" the inner wall of the housing 1.

The housing 1 has at its forward end. an opening bounded by the cylindrical portion 7. This cylindrical portion 7 is provided with one set of inwardly extending lugs 8 in one plane and a second set of relatively inwardly extending lugs 9 in another plane. in the housing 1 may be inserted the parabolic forwardly projecting reflector 10 having at its forward end the outwardly radially extending flange 11 provided with the peripheral notches 12 disposed for registry with the inwardly extending lugs 8. In assembling the reflector 10 in the housing 1, the notches 12 are brought into registry with the lugs 8 and the reflector flange 11 placed in a plane between the plane of the lugs 8 and the plane of the lugs 9. The reflector may then be rotated counter-clockwise to the position shown in Figure 1. To bring the reflector from the position shown in Figure 1 into locked assembled position it is further rotated whereby the lugs 8 pass under the ends of the hump springs 13. These hump springs are mountedbythe eyelets llupon the flange 11 of the reflector. To further lock these hump springs from twisting or turning on the flange 11 each spring has a portion 15 which is passed through an opening 16 to the under side of the reflector flange 11.

This cylindrical housing portion 7 is also provided with a pair of seats or openings 1.7 which may be engaged by the spaced. lugs .18 inwardly extending from the lens ring 19. This lens ring 19 has packing 20 between it and the lens 21. while additional packing 22 is disposed between the lens 21 and the reflector flange 11. This packing takes up lens vibration and seals the lamp against This tough and the entry of dust. To further assist in preventing the lens 21 from working loose, the springs 13 may come into play in helping to frictionally anchor the lens, h

In turning the lens ring into assembled relation, it is moved transversely of the front opening of the housing 1 to bring the" connected therewith, the latch or lever 26 normally held. inwardly orwithdrawn by the hump spring 27. Engaging this lever 26 is the link 28 extending out through the housing for pivotal connection to the cam arm 29, which, in its movement back toward the housing, draws the lever 26 against resistance of the spring 27 through the opening 24 into holding engagement" with; the rib 23, thereby firmly locking the ring 19 on the lamp housing. To obtainaccess to the lamp it is only necessary to rock the camarm .29 past its dead point so that the spring 27' may withdraw the lever aejrrom engagement with the lens" ring or seat 23. The bottom of the lens ring may then be pulled forward and th'en by an upward movement this ring and its adhering' le'ns are freed from the reflector and lamp housing. a i i.

H In the device of Fig. 6 the housing 30 may have its forward cylindrical portion 31' provided with an inwardly extending flange 32 againstwhic'h the outwardly ex tending flange 83 of the reflector 34' may seat. Through this v inwardly extending flange 32 oftheh ous ir'igrnay be the opening 35 for the lever26, no'rmall inwardly with drawn by the spring 27. 1 his lever 26 1nay' have actuation by the spring 27' counteracted through conn'eotion with theflink 28' and a trigger 36, This cam trigger 36- is oppositely placed as to the cam trigger 29 but moves past a dead point to holdf the lever 26 in lens ring engaging position against the inwardly extending rib 37 of the lens ring 38. Theopposite ortremote portions of the lens ring 38' have the inwardly extending rib 37 engaged by the outwardlyv extending hooks 39 of the members 40 anchored in the housing 30. I

The lens ring of Fig. 1' to be brought into mounting positionmust have its angular register while the lens ring of ,6 may,with'ont such angular register but by the simila'r'set of movements, be brought.

into mounting position and finally, locked with a reverse movement of the trigger to the movement of the trigger for the device of Figs; 1 and 5.

The features of construction herein contribute to" lightness and rigidity in the mountingan' assembling of the parts as to the housing in a structure which will withstand the extreme. vibration of motor ve;

Thereis nothing to loosen up It hicle usage: and the parts are strong and well anchored into the desired grouped relation.

That is claimed and it is desired to secure by" lle't'ter's" Patent is 1. A lamp embodying a housing having a. forwardly; extending opening provided with inwardly. extending lugs in different planes, afl refiectfor rotatable into assembled position between said lugs, andspring retainingj means engaging the lugs on one 2 with inwardly extending engaging means, a

reflector having means to co-operate with said engaging means and rotatable intoasseinbled position" in: said housing, and spring retaining means for holding the reflector in assembled position, there being means for fixedly mounting the spring on the re 4'; A lamp embodying a housing having a forwardly extending opening provided with inwardly extending engaging means, a r efiector'having means to co'-'operate with said engaging means and rotatable into assembled position' insaid housing, and -spring retaining means'fo'r holding the reflector in assembled positiomsaid reflector having an eyelet for anchoring: the spring thereto;

5. Alam'p embodying a housing havinga forwardly extending opening provided with inwardly extendingengaging means, reflector. having means to co-ope'rate with said engaging means and rotatable into assembled. position in said housing, and spring retaining means for holding the reflector in assembled position, said spring havingra tongue projecting through a slot formed in said reflector;

6. A lamp provided with a housing, a lens ring provided with seat coacting means movable transversely of the housing into seating position, a holding lever, spring withdrawing means for the lever; a tongue to oppose the spring, and a; self locking cam for reciprooajting'the tongue into ring retaining position. V y

In" witness whereof I affix my signature.

HERMAN R', SAXON.
